    coby ledtv4626 46" LED TV

    Found this while driving home last week. Unfortunately it had started drizzling and by the time I got to it, there was a light misting of rain on the TV. I've spent the last couple of days trying to dry it out. Had a fan blowing on the front and then the back hoping to get it dry.

    Powered it up today and the picture below is what I saw. The lines on the top 40% of the screen are regardless of the input and also show up in the menu.

    My question is: Is this a panel issue or a board issue?

    I would say probably panel, could be down to the tab bonds, which "may" be fixable.

      Would a video help diagnose the issue, or do you need further information from me?
      That's the opposite of what I was hoping for. At least it didn't cost me anything.

        Tons of new LED TVs are dying due to panel fault, cost cutting likely the cause
        Different fault, possibly same cause:

          MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
          by rounin
          Hi everyone,

          I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

          🛠 Original Issue
          The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
          Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

          I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

          ⚠️ New Problem: One USB-C Port Only Works in One Orientation...

          Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
          by ugamazing
          I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

          We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...

          Hello guys!
          I have a strange issue with my laptop keyboard and I'm lost trying to detect what's wrong - the KB9028Q-C or the keyboard itself.
          It powers on OK and has no other issues except the following:
          • CAPS LOCK does not work at all
          • Fn button toggles Flight Mode
          • When I press 't' or '5', it produces 't5', and when I press 'y' or '6', it produces 'y6'
          • (with SHIFT pressed: 't%' and 'y^' respectively)
          I initially thought it was a keyboard malfunction (internal short, etc.),
          but when I press and hold...
